This document describes a high volume floating aerator and mixer produced by DO2E Wastewater Treatment. The aerator is designed to enhance on-site sludge digestion by drawing dormant sludge deposits into the water column and injecting them with dissolved oxygen. It operates using low-pressure, high-volume airflow to maximize oxygen transfer and energy efficiency while aerating and mixing large volumes of water. The aerator is constructed from durable PVC materials and designed for maintenance-free operation, enhanced worker safety, and reduced energy and maintenance costs compared to other aeration equipment.

2. High Volume
Floating Aerator
The DO2E Patent High Volume Floating Aerator /
Mixers are high-efficiency all welded, heavy-duty
PVC devices. These state-of -the- aerators are
designed to pull water from significant depths
for aeration and mixing. On-site sludge digestion
is greatly enhanced by drawing dormant sludge
deposits off the bottom of the lagoon and inject-
ing them with heavy concentrations of dissolved
oxygen. By operating with low-pressure (>2.5 P.S.I.)
high-volume ambient airflow, these devices maxi-
mize oxygen transfer and energy efficiency. These
units are scalable, multi voltage and can be modi-
fied to fit virtually any aeration and mixing applica-
tion.
DO2E utilizes the latest “Green Technology”
and continues to set the standards in the Aera-
tion industry. Our products are designed to be as
maintenance-free as possible. Constructed from
100% heavy-duty marine grade PVC, allows our
units to withstand extreme temperatures and harsh
environments encountered in virtually every waste-
water application. In most installations, Our clients
have realized, enhanced worker safety, mainte-
nance cost reductions up to 95%, and energy sav-
ings of up to 80%. Our product line is the most
energy efficient, maintenance friendly, and cost
effective product introduced to the waste water
market in the past 40 years.
Worker Safety is greatly enhanced by virtu-
ally eliminating man entry into the lagoon. Since
there are no moving parts to wear out, and the fact
that it is secured in place by mooring ropes, there
is no need for man entry into the lagoon. Since the
blowers are land based, operate at low pressure
ambient temperature, and the power can be turned
off and locked-out at the blower location, workers

3. safety is further enhanced. The DO2E aerators
were specifically designed for: worker’s safety,
high oxygen transfer, high water volume move-
ment, energy efficiency, and reduction in main-
tenance cost. Air supply is provided to each
aerator via regenerative air blower placed at a
remote location on land for easy access. With no
electricity in or around the water and no mov-
ing parts, DO2E greatly reduces the worker’s
exposure to risks associated with old and out-
dated aeration equipment used today. DO2E
has designed and patented the safest and most
environmentally friendly aerator / mixer on the
market.
A unique feature of the Aerator system
is its’ expandable capability for the delivery of
various gaseous materials such as ozone, hybrid
ozone with hydroxyl radicals, carbon dioxide,
pure oxygen or other gases required to remedi-
ate various issues. This delivery method allows
us to inject directly into the wastewater stream
allowing for an effective and cost efficient
means of direct treatment in order to address
various issues such as on-site sludge digestion,
and odor control.
All units are designed to address various
issues where aeration is required. The primary
tasks and functions of the aerators/mixers are
to aerate and destratify the water column with
minimum energy consumption. Other tasks are
completed simultaneously including drawing
from various water depths, breaking up sludge
deposit into smaller particulates, de-stratifying
the water column, producing high levels of dis-
solved oxygen and depositing solids into specif-
ic zones or areas. “Ozone”, one of the strongest
oxidants readily available can be added to the
units to address both recalcitrant particulates
and noxious microorganisms, including a wide
variety of pathogens. “Ozone” also causes the
oxidation of sulfides for enhanced odor-control.
All DO2E Aerators draw water into the
device by means of the Venturi effect with no
bottom scoring or no negative affects to lagoon
liners. Water is then expelled through the upper
chambers. This process creates a vacuuming
effect drawing sludge deposits into the process
chamber where they are injected with high
levels of oxygen or in some cases, ozone. This
process greatly accelerates the digestion of
heavy sludge deposits that are sitting dormant
on the bottom of the pond or lagoon. Our pat-
ented aeration tubes are designed to deliver
a unique combination of coarse, medium, and
fine bubbles which when released at a specific
depth, draws the water in through the bottom of
the unit. Water is pulled upward being aerated
all the while and redirected into a horizontal
flow across the highly oxygenated upper portion
of the water column.

The Patented High Volume State of the Art Aerator injects high volume, low-pressure
air through a specially designed multi chambered air manifold located at the bottom of the
unit. This unit creates a surface current up to 3 knots for a distance of up to 100 ft.
Using a unique combination of coarse air and fine air bubble aeration, we are able
to move high volumes of water (up to 24.1 million gallons per day), while at the same time
transferring high volumes of dissolved oxygen throughout the water column. The fine air
bubbles maximize the oxygen transfer while the coarse air bubbles provide the ultimate
velocity.
The unique combination of coarse and fine air bubbles released at a specific water
depth within a confined space allows for a highly efficient aeration and mixing.
The unit can operate in as little as 4’of water and can draw from depths
of up to 16’of water.
